The invention relates in particular to compositions for caring for or making up said keratinous substances.

The invention relates to a cosmetic method for making up and/or caringfor keratinous substances, in particular the skin, comprising theapplication to said keratinous substances of a cosmetic compositioncomprising a siloxane resin and a volatile hydrocarbon solvent. Theinvention relates in particular to compositions for caring for or makingup said keratinous substances.

A makeup product is used to contribute color to the skin, to mattify andto homogenize the complexion. The consumer also expects the result ofthe makeup to be stable over time and in particular over the course ofthe day.

It is known to a person skilled in the art to use several formulationroutes in order to obtain a makeup result which is stable over time. Theformulator can thus introduce sebum-absorbing fillers, silicone resinsor also volatile silicone solvents, such as cyclopentasiloxane.

The use of these starting materials can be accompanied by discomfort ofthe makeup (in particular characterized by feelings of tightness of theskin), either immediately after application of the product or during theday.

It thus appears necessary to provide a technical solution which makes itpossible to obtain a makeup result which is stable over time, inparticular over the course of the day, while retaining comfortable use,both during application and after making up, in particular during theday.

It has been found, unexpectedly, that it is possible, by combiningsiloxane resins with volatile solvents, more particularly volatile C₈ toC₁₆ hydrocarbon solvents, to obtain a product which is comfortable toapply and which confers a makeup result which is stable over time.

This aim and others are achieved by the present invention whichdescribes in particular a cosmetic method for making up and/or caringfor keratinous substances, in particular the skin, comprising theapplication, to said keratinous substances, of a composition comprising,in a physiologically acceptable medium:

-   -   i) at least one siloxane resin comprising the units:        -   (i) (R¹ ₃SiO_(1/2))_(a)        -   (ii) (R² ₂SiO_(2/2))_(b)        -   (iii) (R³SiO_(3/2))_(c) and        -   (iv) (SiO_(4/2))_(d)            with    -   R¹, R² and R³ independently representing an alkyl group having        from 1 to 8 carbon atoms, an aryl group, a carbinol group or an        amino group,    -   a being between 0.05 and 0.5,    -   b being between zero and 0.3,    -   c being greater than zero,    -   d being between 0.05 and 0.6,    -   a+b+c+d=1,        provided that more than 40 mol % of the R³ groups of the        siloxane resin are propyl groups, and    -   ii) at least one volatile C₈ to C₁₆ hydrocarbon solvent.

The method according to the invention makes it possible toadvantageously obtain deposited layers having a good persistence of thecolor throughout the day, while retaining a good level of mattness. Thecombination according to the invention has turned out to exhibit verygood properties of persistence of the color while retaining a mattdeposited layer comfortable for complexion applications, which is aparticularly noteworthy result.

The siloxane resins which can be used according to the invention can beobtained by a process comprising the reaction between:

-   -   A) an MQ resin comprising at least 80 mol % of (R¹        ₃SiO_(1/2))_(a) and (SiO_(4/2))_(d) units,        -   R¹ representing an alkyl group having from 1 to 8 carbon            atoms, an aryl group, a carbinol group or an amino group,            -   a and d being greater than zero,            -   the ratio a/d being between 0.5 and 1.5;                and    -   B) a propyl T resin comprising at least 80 mol % of        (R³SiO_(3/2))_(c) units,        -   R³ representing an alkyl group having from 1 to 8 carbon            atoms, an aryl group, a carbinol group or an amino group,            -   c being greater than zero,        -   provided that at least 40 mol % of the R³ groups are propyl            groups,            where the A/B ratio by weight is between 95:5 and 15:85.

The component A) is an MQ resin comprising at least 80 mol % of (R¹₃SiO_(1/2))_(a) and (SiO_(4/2))_(d) units, where R¹ is as defined above,i.e. represents an alkyl group having from 1 to 8 carbon atoms, an arylgroup, a carbinol group or an amino group, a and d are greater than zeroand the ratio a/d is between 0.5 and 1.5.

The MQ resins which can be used as component A) and their method ofpreparation are known from the prior art. For example, U.S. Pat. No.2,814,601, belonging to Currie and al., dated Nov. 26, 1957 describes aprocess for manufacturing MQ resins by conversion of a water-solublesilicate into a silicic acid monomer or a silicic acid oligomer by usingan acid. Once the appropriate polymerization has been carried out,trimethylchlorosilane ends are introduced in order to obtain the MQresin. Another process of preparation of MQ resins is described in U.S.Pat. No. 2,857,356, belonging to Goodwin, dated Oct. 21, 1958. Goodwindescribes a process for the manufacture of an MQ resin by cohydrolysisof a mixture of an alkyl silicate and of a trialkylsilaneorganopolysiloxane which can be hydrolyzed with water. The MQ resinssuitable as component A) in the present invention can comprise D and Tunits, provided that at least 80 mol %, indeed even 90 mol %, of thetotal siloxane units are M and Q units. The MQ resins can also comprisehydroxy groups. The MQ resins can thus comprise hydroxy groups in atotal amount by weight of between 2 and 10%, preferably between 2 and5%. The MQ resins can also comprise additional ends, residual hydroxygroups being for this reacted with the M groups.

The component B) is a propyl T resin comprising at least 80 mol % of(R³SiO_(3/2))_(c) units, R³ being as defined above, i.e. representing analkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinolgroup or an amino group, c being greater than 0, provided that at least40 mol % of the R³ groups are propyl groups.

The component B) can thus be obtained by hydrolysis ofpropyltrimethoxysilane, propyltriethoxysilane or propyltripropoxysilaneor by cohydrolysis of the abovementioned propylalkoxysilanes withvarious alkoxysilanes. Mention may be made, as examples of thesealkoxysilanes, of methyltrimethoxysilane, methyltriethoxysilane,methyltriisopropoxysilane, dimethyldimethoxysilane andphenyltrimethoxysilane.

The propyl T resinscan also comprise hydroxy groups. Preferably, the propyl T resinscomprise between 3 and 8% by weight of hydroxy groups.

A polyorganosiloxane can also be added to the process according to theinvention as component C).

The polyorganosiloxanes of use as component C) according to theinvention comprise R² ₂SiO_(2/2) or R³SiO_(3/2) units. Thepolyorganosiloxane can be added in order to introduce various D and Tunits into the MQ-propyl T resins, in order to modify the properties ofthe resulting resins. The structure or the formula of thepolyorganosiloxane is not limiting, provided that saidpolyorganosiloxane comprises a measurable amount of R² ₂SiO_(2/2) orR³SiO_(3/2) units and that the total amount of polyorganosiloxane addedto the reaction between A) and B) does not result in more than 50 mol %of D or T units in the reaction mixture.

The polyorganosiloxane can comprise combinations of M, D, T and Q units,provided that at least the D or T units are present. Thus, thepolyorganosiloxane can be chosen from silicone fluids, gums or resinsknown from the prior art and comprising D or T units, or their mixtures.

The D units typically comprise methyl or phenyl groups or their mixturesas R² groups. The T units typically comprise methyl or phenyl groups ortheir mixtures as R³ groups.

Inparticular, the L/D ratio (or aspect ratio) is chosen within the rangefrom 3.5 to 2500, preferably from 5 to 500 and better still from 5 to150.

The fibers which can be used in the composition of the invention can befibers of synthetic or natural and inorganic or organic origin. They canbe short or long, individual or organized, for example braided, andhollow or solid. They can have any shape and can in particular becircular or polygonal (square, hexagonal or octagonal) in cross section,according to the specific application envisaged. In particular, theirends are blunted and/or polished to prevent injury.

In particular, the fibers have a length ranging from 1 μm to 10 mm,preferably from 0.1 mm to 5 mm and better still from 0.3 mm to 3 mm.Their cross section can be included within a circle with a diameterranging from 2 nm to 500 μm, preferably ranging from 100 nm to 100 μmand better still from 1 μm to 50 μm. The weight or count of the fibersis often given in denier or decitex and represents the weight in gramsper 9 km of yarn. Preferably, the fibers according to the invention havea count chosen within the range from 0.01 to 10 denier, preferably from0.1 to 2 denier and better still from 0.3 to 0.7 denier.

The fibers can be present in the composition in a content ranging from0.1% to 30% by weight, with respect to the total weight of thecomposition, preferably ranging from 0.1% to 20% by weight andpreferentially ranging from 0.1% to 10% by weight.

The composition according to the invention can also comprise ingredientscommonly used in cosmetics, such as vitamins, thickeners, traceelements, softeners, sequestering agents, fragrances, basifying oracidifying agents, preservatives, sunscreens, surfactants, antioxidants,agents for combating hair loss, antidandruff agents, propellants, ortheir mixtures.

Of course, a person skilled in the art will take care to choose this orthese optional additional compounds and/or their amounts so that theadvantageous properties of the corresponding composition according tothe invention are not, or not substantially, detrimentally affected bythe envisioned addition.

According to another aspect, the invention also relates to a cosmeticcombination comprising:

-   -   i) a container delimiting at least one compartment, said        container being closed by a closing element; and    -   ii) a composition positioned inside said compartment, the        composition being in accordance with the invention.

The container can have any appropriate form. It can in particular be inthe form of a bottle, a tube, a pot, a box, a tin, a bag or a case.

The closing element can be in the form of a removable stopper, of a lid,of a seal, of a tear-off strip or of a capsule, in particular of thetype comprising a body fixed to the container and a cap articulated overthe body. It can also be in the form of an element providing theselective closure of the container, in particular a pump, a valve or aflap.

The container can be used in combination with an applicator, inparticular in the form of a brush comprising an arrangement of hairsheld by a twisted wire. Such a twisted brush is described in particularin patent U.S. Pat. No. 4,887,622. It can also be in the form of a combcomprising a plurality of application elements, obtained in particularfrom molding. Such combs are described, for example, in patent FR 2 796529. The applicator can be in the form of a fine brush, such asdescribed, for example, in patent FR 2 722 380. The applicator can be inthe form of a pad of foam or elastomer, of a felt-tipped pen or of aspatula. The applicator can be free (powder puff or sponge) orintegrally attached to a rod carried by the closing element, such asdescribed, for example, in patent U.S. Pat. No. 5,492,426. Theapplicator can be integrally attached to the container, such asdescribed, for example, in patent FR 2 761 959.

The product may be contained directly in the container or indirectly. Byway of example, the product can be positioned on an impregnated support,particularly in the form of a wipe or of a wad, and can be positioned(singly or severally) in a tin or in a bag. Such a support incorporatingthe product is described, for example, in application WO 01/03538.

The closing element can be coupled to the container by screwing.Alternatively, the coupling between the closing element and thecontainer is carried out other than by screwing, in particular via abayonet mechanism, by snapping, clamping, welding or adhesive bonding,or by magnetic attraction. The term “snapping” is understood to mean inparticular any system involving the crossing of a row or strip ofmaterial by elastic deformation of a portion, in particular of theclosing element, and then by elastically returning said portion to theunstressed position after the row or strip has been crossed.

The container can be at least partially made of thermoplastic material.Mention may be made, as examples of thermoplastic materials, ofpolypropylene or polyethylene.

Alternatively, the container is made of non-thermoplastic material, inparticular of glass or of metal (or alloy).

The container can have rigid walls or deformable walls, in particular inthe form of a tube or of a tube bottle.

The container can comprise means intended to bring about or facilitatethe distribution of the composition. By way of example, the containercan have deformable walls, so as to bring about the departure of thecomposition in response to excess pressurization inside the container,which excess pressurization is brought about by the elastic (ornon-elastic) crushing of the walls of the container. Alternatively, inparticular when the product is in the form of a stick, the latter can bedriven by a piston mechanism. Still in the case of a stick, inparticular of a makeup product (lipstick, foundation, and the like), thecontainer can comprise a mechanism, in particular a rack-and-pinionmechanism or a mechanism with a screw rod or a mechanism with a helicalgroove, capable of moving a stick in the direction of said opening. Sucha mechanism is described, for example, in patent FR 2 806 273 or inpatent FR 2 775 566. Such a mechanism for a liquid product is describedin patent FR 2 727 609.

The container can be composed of a case with a bottom delimiting atleast one receptacle comprising the composition and a lid, in particulararticulated over the bottom, capable of at least partially covering saidbottom. Such a case is described, for example, in application WO03/018423 or in patent FR 2 791 042.

The container can be equipped with a drainer positioned in the vicinityof the opening of the container. Such a drainer makes it possible towipe the applicator and optionally the rod to which it may be integrallyattached. Such a drainer is described, for example, in patent FR 2 792618.

The composition can be at atmospheric pressure inside the container (atambient temperature) or pressurized, in particular using a propellantgas (aerosol). In the latter case, the container is equipped with avalve (of the type of those used for aerosols).

The contents of all the patents or patent applications mentioned aboveare incorporated by reference in the present patent application.

EXAMPLES Example 1 Preparation of an MQT^(Pr) Resin

The following resins are used:

Resin MQ=an MQ resin of formula M_(0.43)Q_(0.57) and with M_(n)=3230dissolved in xylene at 70.8% by weight of solids. The MQ resin wasmanufactured according to the techniques described by Daudt in patentU.S. Pat. No. 2,676,182.

Propyl T resin=a propyl silsesquioxane resin at 74.8% by weight intoluene. The propyl silsesquioxane resin was obtained by hydrolysis ofpropyltrichlorosilane.

An MQ resin, a propyl T resin, xylene and 1M KOH in water, in theproportions shown in table 1, are introduced into a three-necked flaskequipped with a stirrer, with a temperature probe and Dean and Starkapparatus equipped with a condenser at the top. Xylene is preintroducedinto the Dean and Stark apparatus in order to ensure that a level ofsolids at 50% is maintained in the reactor. The mixture in the reactoris maintained at a reflux temperature (between 100 and 140° C.) for atleast 3 hours. Any water which is formed in the reaction mixture iscontinuously removed, if appropriate, and trapped in the form of anazeotrope in the Dean and Stark apparatus. After refluxing for 3 hours,the water is removed from the apparatus and heating is continued for anadditional 30 minutes. After cooling the mixture, an excess of aceticacid is added in order to neutralize the KOH in the mixture. The mixtureis subsequently filtered, in order to remove the salts formed, bypassing it through a filter under pressure. A solvent exchange iscarried out by heating the mixture in a rotary evaporator under vacuum.After removing the majority of the xylene, decamethylcyclopentasiloxaneor isododecane is added while continuing to remove any residual aromaticsolvent. The structures of the resulting siloxane resins arecharacterized by ²⁹Si NMR spectroscopy and GPC and the results aresummarized in table 2 below.

Procedure

The constituents of phase A2 are weighed out. The mixture is passedthrough a triple roll mill.

The constituents of phase A1 are subsequently weighed out into the mainbeaker and the latter is placed in a water bath (75-80° C.). When themixture is homogeneous, it is cooled to ambient temperature.

A2 is incorporated in phase A1 with stirring with a Moritz stirrer at1500 revolutions/min.

The constituents of phase A3 are then successively added while retainingthe same stirring.

The constituents of phase B are weighed out. Phase B is brought toboiling, until the constituents have completely dissolved. Phase B iscooled to 50° C.

Phase B is subsequently trickled into phase A1+A2+A3 while stirring witha Moritz stirrer at 3200 rev/min.

Protocol for Instrumental Measurements of the Immediate Mattness and thePersistence of the Mattness

The mattness and the persistence of the mattness after application ofsaid composition to the skin of the face can be measured using theprotocol described below.

The mattness of a region of the skin, for example the face, is measuredusing a polarimetric camera, which is a black and white polarimetricimaging system, with which images are acquired in parallel (P) andcrossed (C) polarized light.

By analyzing the image resulting from the subtraction of the two images(P-C), the shine is quantified by measuring the mean level of gray ofthe 5% of shiniest pixels corresponding to the regions of shine.

More specifically, the measurements are carried out on a panel ofindividuals who are kept in an air-conditioned (22° C.+/−2° C.) waitingroom for 15 min before the beginning of the test. They remove theirmakeup and an image of one of their cheeks is acquired with thepolarimetric camera. This image makes it possible to measure the shineat T0 before applying makeup. Approximately 100 mg of said compositionas described above are then weighed out into a watch glass and areapplied with the bare fingers to the half of the face on which the T0measurement was carried out.

After a drying time of 15 min, an image of the made-up cheek is acquiredwith the polarimetric camera. This image makes it possible to measurethe shine immediately after applying makeup (Timm). The models thenreturn to the air-conditioned room for 3 h.

Finally, an image of the made-up cheek after waiting for 3 h is acquiredwith the polarimetric camera. This image makes it possible to measurethe shine after wearing makeup for 3 h (T3h).

The results are expressed by calculating the difference (Timm−T0), whichmeasures the effect of the makeup. A negative value means that themakeup reduces the shine of the skin and that it is thus mattifying.

The difference (T3h−Timm) measuring the persistence of this effect issubsequently calculated. The value obtained should be as low aspossible, which means that the mattness of the makeup does not changeover time.

For the measurements carried out, it is considered that:

+ slight effect or low persistence++ moderate effect or moderate persistence+++ significant effect or good persistence++++ very significant effect or very good persistence

Protocol for Instrumental Measurements of the Immediate Color and thePersistence of the Color

The same protocol as that described above for the mattness is used but,instead of measuring the shine, a colorimetric measurement of the skin,before and after applying makeup, is carried out by measuring the a*, b*and L* indices, namely the red and yellow indices and the brightness.

For each woman, an image of the cheeks is taken at T0 (before applyingmakeup), at Timm (15 minutes after applying makeup of said composition)and at T3h (3 h after applying makeup), using a chromasphere, with adefinition of 410×410 pixels.

Each image obtained with the camera is made use of in color. The coloris quantified by the red and yellow indices, the brightness and thecolor difference (respectively a*,b*, L* and deltaE).

The deltaE, dE or ΔE is defined as a measurement of difference betweentwo colors. The formula established in 1976 is shown below:

ΔE*=√{square root over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}{squareroot over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}{square root over (((L₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}, where:

L₁, a₁ and b₁ are the coordinates in the colorimetric space of the firstcolor to be compared and L₂, a₂ and b₂ those of the second.

Results

-   -   color persistence measurements: (T3h−Timm) grading ++++ (very        good)    -   mattness persistence measurements: (T3h−Timm) grading +++ (good)

Very good results in terms of persistence of the color and persistenceof the mattness are obtained.

Furthermore, a sensory evaluation of said emulsion (W/O) was carried outon a panel of individuals who use foundation. After free application ofsaid composition to the face, each individual evaluates the perceptionof said composition at the time of application and in terms of makeupresult. Said composition is graded favorably: the softness of thematerial allows homogeneous distribution over all the regions; thefoundation offers a mattifying result; the foundation is comfortable towear and is completely forgotten.
